Has anyone thought of this? I remember, one thing that made the social network sites, especailly facebook so popular is that if your friends try and invite you and your not on it, you get bombarded with emails saying stuff like "Your friend suchandsuch is trying to contact you, do you want to create an account today to contact them back?"... What if we had an escrow service, that allowed sending BitCoins direct to email address, so that people receive an email such as "Your friend suchandsuch is trying to send you X amount of BTC, do you want to create a wallet to download them now?" ... Of course theres the problem of trust in the service, but for small transactions, it seems feasible and will spark interest in BitCoins... What do people think?

EDIT: Also, on second thought, I was thinking what would this be useful for... My initial thoughts would be giving to friends, getting the word out on BitCoins, sending gifts for birthdays/weddings to people you only know their email addres, donations to charities or organisations... It probably wouldnt be useful for trying to trade with say Amazon.com, but if they got enough emails spamming them about BitCoin, perhaps they will stand up and take notice... I say, if everyone donates 0.001 BTC to amazon, we could start a protest to get them to accept them... They would be foolish to just ignore it...

Want to tip someone who is not on Youtipit?You can create a tipit for a person you think should receive tips but is not a member of Youtipit yet. Its easy, just create an Escrow tipit for them. All you need is thier Facebook profile URL and some bitcoins in your Youtipit account to tip them with. Once the tipit is created other people will be able to tip them and the person can claim the tipit at any time by registering with thier facebook account.
